Circuit Description

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

The mobility seat module monitors an input from a hall effect sensor in the rotation motor while the seat is being rotated in or out. The hall effect is a 12-volt 3-wire sensor and the signal circuit is referenced from battery voltage within the module.
